STREET-RAILWAY `(10N STRUCTICN.

Specification of Letters Patent. Patgntd Aug. 10, 1920.

Application filed. February 14, 1919. Serial No. 277,064.

To all 'LU/2.0m t 'may concern Be it known that I, VIILLIAM S. Gonwrn, acitizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Street-Railway Constructiomof which the following is aspecification. i

This invention relates to improvements in street railway construction,and more particularly to a between-rails paving guard.

The primary object of the invention is to provide a paving guard which,with the rail, forms a groove to accommodate the flange of the wheel,the guard being heldin place by the paving.

A `further object of the invention is to provide a guard which isunattached to the rail base, so that the vibrations of the rail will notbe imparted to the paving, thereby reducing injury to the pavingadjacent the rails to a minimum.

A still further object of the invention is to provide a rail fillerhaving a strip of elastic material interposed between the head of therail and the iiller, to prevent the shock of traffic from shattering thefiller, the arrangement of the filler with relation to the guard beingsuch as toprevent also the injurious effects of` water seeping in underthe rail tread above the filler.

The standard T-rail has proven, by service, to be preferable to thegirder-tram rail, or the girder-groove rail. The first cost of thestandard `T-rail, also 'the maintenance cost, is considerably less thanthe cost of the tranrrail and the groove-rail. T-rails are not, however,satisfactory in paved.

streets, as their use does not permit-of the necessary smooth continuityof the pavement. I have therefore, devised the construction of guardillustrated, which when used in connection with the standard T-rail,provides the necessary groove-way for the wheel iange and also thenecessary protection for the paving, the completed constructionpermitting the desired surface smoothness, and a desired condition inall respects with regard to team traiiic that is incident to the use ofrail.

Another object of the invention is to provide a convenient form ofanchor which, coperating with the peculiar guard construction, maintainsthe guard rmly in the ordinary girder-groove` place, in the paving, theconstruction being such that the anchor or anchors not only serve tokeep the guard lirmly in place, but at guard joints, serve to keep theguard in perfect alinement, all as will appear in the course of thefollowing description. V -In the drawings illustrating the inven tion, nFigure 1 is a section of a portion of a street or roadway adjacent therail;

Fig. 2 is a side view of the guard, there being shown the ends of twoguards in proper relation to each other, the anchors in this view beingslightly raised in order to show more clearly their contour;

Fig. 3 is a sectional view of a street or roadway, showing a T-railconstruction with modiiiedform of guard and anchor, and

Fig. 4 is a similar' view, with still another modified form of guard andanchor;

Fig. 5 is a detail section of a portion of a street or roadway, showingVanother form of guard, and

Fig. 6 is an elevation showing the iiat side of the guard or the anchorportion.

Referring to the drawings, the numeral 1 designates the cross-tie, whichmay be of` wood or metal and of any suitable or approved construction.This tie rests upon a suitable foundation such as soil,v ballast,concrete, etc. The numeral '2 'designates a standard T-rail with thebase resting on the tie 1.

The numeral 3 designates the paving base, preferably of concrete, andthe numeral 4; the wearing surface of asphalt or any other suitablematerial.' The numeral `5 designates a pavingguard, which is made insuitable iengths, and which extends parallel with the rail and isprovided at intervals,

with anchors 6, which are embedded in the concrete, to hold the guard 5in place, the guard forming a boundary for the wearing surface of thestreet, and being so positioned with regard to the rail, as not to havethe vibrations of the rail transmitted thereto.

This construction is fully described and claimed in Patent Number1,246,907, granted November 17, 1917, and has to do with pavingconstruction outside the rails, and4 need not therefore, be furtherreferred to in this application, since in this application the inventionresides in the between-rails construction, which will be now describedin detail.

The numeral `7 designates the roadway base, preferably of concrete, orthe same Inaterial as that which composes the paving base on the outsideof the rails. rThis base is formed between the rails and extendssubstantially for the entire distance between them, and supports awearing surface 8 of asphalt, concrete, blocks, or other suitable Ymaterial. The numeral 9 designates the metallic guard, which is made insectionshof very considerable length. The under side of the guard, at apoint farthest from the rail, is provided with a longitudinal groove 10,and a downwardly extending vertical portion 11. The numeral 12designates a yoke-shape anchor, preferably round in cross section, andadapted to be received in the groove 10 of the guard. At intervals, theguard is slit or cut as indicated at 13, the cut portions being adaptedto be bent under the horizontal portion of the yoke, to firmly securethe guard and anchors together. The downwardly extending arms of theanchors are embedded in the concrete base 7 and the base, adjacent tothe rails is so shaped as to completely fill in under the downwardlycurved or projecting flange 1d of the guard, this flange of the guardbeing so shaped and positioned relative to the rail, as to provide` agroove 15 for the flange 1G of the wheel. VThe rail is provided on bothsides with a filler of suitable material, preferably concrete, asindicated by the n-umerals'17,and 18, the outer faces of the. fillerbeing in line with the outer edges ofthe tread er head of the rail, asshown, and extend to the base of the rail. interposed between the topsof the fillers and the underside of the tread, are strips of asphalt orother' elastic material 19, which permit of the vertical expansion andcontraction of the filler, thus eliminating the likelihood of crackingor disintegration of the fillers, due to temperature variations, andvibrations due to traffic. rllhey also absorb the shock of traffic, andprevent chipping of the filler. Y

The edge of the guard adjacent the rail is provided with a shortdownwardly extending flange 20, which rests snugly against the face ofthe rail filler.

Attention being particularly called to 2, it will be noted that ananchor is attached to the guard, nearthe ends of the guard, there beingprovided at or near the ends, the ears 13, which, as before suggested,are bent under the horizontal portion or top portion of the anchor,thereby causing the anchors to serve, not merely as anchors by which theguard is held firmly in place by the concrete base, but also to keep theguard sections in true alinement. It will be further understood thatseveral of these anchors, depending upon the length of the guardsections, are provided for each guard, there being provided thenecessary ears at inten vals to embrace the upper portion of theanchors.

In constructing the portion of the pavement adjacent to the rail, theguardis first placed in position adjacent to the rail and the concreteis then formed under the guard, and then the wearing surface of asphalt,or other suitable material, is placed on the base, to the desiredthickness, until its' upper surface or line is flush with the upper faceof the guard. y

The construction is one in Vwhich it will be noted that the rail restsentirely upon thecross-tie, as in my patent hereinbefore referred to,and that the base of the between-rail portion of the roadway or theconcrete 7 is in no way attached. to the'cross tie, consequently,vibrations of the tie', due to traffic, will not be transmitted to theguard, and consequently the paving adjacent the guard will not beinjured, as in cases where the guard is tied to the crosstie, or toplates or other members carried by the cross tie, or rail.

ItA will be noted that the lower portion of the guard, adjacent therail, has its upper surface about on line with the filler 18,

which is interposed between the strip of elastic material 19 and therail base on the guard side; of the rail, thu-s preventing water, whichmay accumulate in the groove formed by the rail and paving guard, fromseeping down between the filler and the concrete base 7.

It will be understood that theanchor arms 12 may be twisted or providedwith roughfconvenient length, but this guard is intend ed for use instreet construction where the paving between the rails is not brought tothe level ofthe top of the tread of the rail. These guards in suchconstruction are pro vided centrally with a downwardly extending flangeor web 22, which extends into the concrete base 7, and .at intervalsanchors 23 are formed or attached, either by welding, or any othersuitable means. r-ihese anchors may be flat pieces, twisted asindicated, sov as to get a firm hold in the concretebase. As in the caseof theipreferred form of guard, or the groove rail construction, theanchors are not in any way connected with the cross tie, consequentlythe vibrations of the rail, due to traffic, are taken up by the crosstie and not imparted to the guard. Y

In Fig. 1,still another form of paving guard is shown, this being aguard made in,

sections of convenient length, ,with flat upper surface, and downturnedflanges 24k and 25, to which anchors 26 andZT are attached or formedat'intervals in the same manner asthat described in connection with thetion whatever' with the cross ties.

ln this construction, the strips of elastic material above'the railfillers are employed and the bottom of the strips on the guard side ofthe rail, are in line with the top surface or tread portion of theguards, thus, as in the preferred form, preventing water from seepine inabove the fillers.

Referring to 2illigs. 5 and 6, the guard 28 is formed with a continuousHat vertical portion 29 slit at opposite angles, as indicated at 30, toform ears 31 which are bent in staggered order, which formation enablesthe concrete to fill in between the ears, and thus more firmly lock theguard in pla-ce.
